- Painter's tape
- Cardboard, tabletop, or other flat surface
- Toy cars
- Test the painter's tape on your surface, whether it's cardboard, a floor, or a table, to ensure the surface won't be damaged.
- Once you're sure the tape won't affect the surface, map out roadways with tape. Roads can be as long or as short as you want—you could even make an entire room into a complex traffic system!
- Play with toy cars on the tape roads and have fun!
